SPECIFICATION forming; part of Lettersrateneno. 595,465, dated' December 14, 1897.

Appliance nea ny'z'l, 18ev and useful Improvements in Velocipedes, ,of`

which the following, taken in connection with the accompanying drawings, is afull, clear, and exact description.

My invention relates to improvementsv in velocipedes of the class set yforth in my pending application, Serial No. 570,067, and has for its object the production of a practical 4and simple device which permits ready ad-` justment of the handle-bar and removal of its standard and firmly secures said handlebar'and standard in operative position; and

to this end it consists, essentially,in the general construction and arrangement of the handle bar, its supportingstandard, and the means for engaging theV handle-bar and its standard and holding the same in their adjusted position, all as hereinafter fully described, and pointed out in the claims.v

In describing thisinvention reference is had to the accompanying drawings, forming a part of this specification, in which-like letters indicate corresponding parts in all the views.

Figure 1 is a top plan of the central portionV of my improved handle-bar, its supportingstandard, and the upper end of the headof the velocipede. Fig. 2 is an enlarged vertical section taken on line 2 2, Fig. 1. Fig. 3 isa transverse section taken on line 3 3, Fig. 2.

ing its lower end formed hollow and itsupper end provided with a transverse eye b for receiving the handle-bar and an opening b',

which extends upwardly from said eye and isA preferably formed circular. The perforation a receives an operating-piece, presently described, and is formed of greater length than width, as best seen at Fig. 5, for permitting a limited adjustment of the handle-bar on e". sean No'. 51925471. (no man.)

said operating-piece. The lower end of the standardB is provided with suitable slots b2, `which preferably extend lengthwise thereof, and is flrmly'securedwithin a hollow upright, as a fork-standard C, connected in any desired manner, as by a ball-bearing c, to the head c' of the velocipede or other device to which my invention is applied.

Dis a suitable clamping-piece, which is opening b', and` is provided with a substantially upright aperture d, extending therethrough. The upper face of the clampingis formed concave and is provided with transd verse serrations d', which engage the serrations d of the handle-bar. Theserrations d `at thev front and rear of the clamping-piece and the adjacent serrations c are preferably formed-with substantially vertical faces d2 a2, 3 as best seen at Figs. .6 and 7, for facilitating `vertical adjustment of the clamping-piece. Asuitable operating-piece E forces the clamping-piece into operative engagement with the handle-bar, and, as best seen at Fig. 2, the `lower end of said operating-piece is screw- `threaded and engages with a nut, presently described. The upper end of said operating- .the aperture d and is provided with a shoulface of theclamping-piece. k

F is an expansion-plu g, which is preferably ,formed hollowy and is utilized to secure the standard B in position, and G is the nut, J previouslymentioned, engaged with the lower l end of the operating-piece E for forcing said plug into operative position. The plug F is .preferably formed cylindrically, isarranged wit'hin the slotted portion of the standard B, Y and its lower end is preferably provided with an annular shoulder f, engaged with the lower edge of the standard B, for limiting upward imovement of the plug. The upper end of said plug is formed` with slots f', extending :downwardly from its top face, and interposed :spring portions or arms f2, movable outwardly fagainsttheinuer face of the standardA and `.hav-ing inner engaging faces f3 inclined up- .wardly toward each other. The nut Gr is formed witha -conical upper end for engaging the faces f3 and forcing outwardly the piece D is substantially fiat, and its lower face' piece is passed through the perforation c' and usually'formed cylindrical, is arranged in the der e, engaged with the top substantially flat IOO portions or arms f2 as the operating-piece is revolved and elevates said nut. A suitable spring F is preferably utilized for normally engaging the upper end of the nut G with the faces f3 and thereby preventing revoluble movement of said nut as the operating-piece E is revolved. The tension of said spring may be varied by a screw-plug E2, which is engaged with screw-threads in the inner peripheral face of the expansion-plug F and also forms a support for said spring.

In the operation of my invention the operating-piece E is revolved for loosening the clamping-piece D and depressing the nut G to permit the outwardly-movable portions or arms of the expansion-plug to assume their normal position. The handle-bar may then be raised or lowered by similarly moving its standard, and its ends may be raised or lowered by slightly rocking the handle-bar in the eye b, or the operating-piece may be removed for permitting semirotation of the handle-bar in said eye. After the desired adjustment of the handle-bar the operating-piece is forced to its normal position, whereupon the handlebar and its standard are firmly and positively held in their adjusted position.

My invention will now be readily understood upon reference to the foregoing description and the accompanying drawings.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination of a supporting-standard having its lower end formed hollow and its upper end provided with an eye and an opening extending outwardly from the inner face of the eye through the outer peripheral face of said eye, a handle-bar mounted in the eye and provided with a vsubstantially upright perforation extending from front to rear and formed of greater length than width, a clamping-piece provided with an aperture and having one end arranged in said opening and formed with a concave lower face for engaging the handle bar, and its opposite end formed with a substantially flat upper face, a bolt for operatively engaging the clampingpiece with the handle-bai', said bolt being passed through the aperture in the clampingpiece and the perforation in the handle-bar, and having one end engaged with the upper face of the clamping-piece and its opposite end extended into the hollow portion of the standard, and a nut adjustable lengthwise on the bolt within the hollow portion of the standard, said nut being connected to the standard, substantially as and for the purpose described.

2. The combination of a supporting-standard having an expansible inner end, and an eye at its outer end provided with an opening extending outwardly therefrom, a handle-bar mounted in the eye, a clamping-piece arranged within said opening for engaging the handle-bar, a nut supported within the inner end of the standard and operating to expand said end, and a revoluble operating-piece for actuating the clamping-piece and the' nut, substantially as and for the purpose specified.

3. The combination of a supporting-standard having a portion thereof expansible, a substantially cylindrical expansion-plug arranged within the expansible portion of the standard and provided with outwardly-movable portions or arms having engaging faces, a nut for forcing said portions or arms outwardly, a revoluble operating-piece within the standard engaged with the nut for elevating the same, and a spring for forcing the nut against said engaging faces, substantially as and for the purpose set forth.

4. The combination of a supporting-standard having a portion thereof expansible,a substantially cylindrical expansion-plug arranged within the expansible portion of the standard and provided with outwardly-movable portions or arms having engaging faces, a nut for forcing said portions or arms outwardly, a revoluble operatingpiece within the standard engaged with the nut for elevating the same, a spring for forcing the nut against said engaging faces, and a screw-plug movable lengthwise in the expansion-plug for supporting the spring, substantially as and for the purpose specified.

5. The combination of a supporting-standard having a portion thereof expansible, a substantially cylindrical hollow expansionplug arranged within the expansible portion of the standard, and having its lower end formed with an annular shoulder engaged with the standard for limiting the upward movement of the plug, the upper end of said plug being provided with outwardly-movable portions or arms having engaging faces projecting upwardly and inwardly toward each other, a nut having the outer surface of its upper end inclined upwardly and inwardly for engaging said faces and forcing the movable portions or arms of the plug outwardly, and an operating-piece within the standard engaged with the nut for elevating the same, substantially as and for the purpose described.

6. The combination of a supporting-standard having a portion thereof expansible, a substantially cylindrical expansion-plug arranged within the expansible portion of the standard, and having its lower end formed with an annular shoulder engaged with the standard for limiting the upward movement of the plug, the upper end of said plug being provided with outwardly-movable portions or arms having engaging faces projecting upwardly toward each other, anut havinga tapei-ing upper end for engaging said faces and forcing the movable portions or arms of the plug outwardly, an operating-piece within the standard engaged with the nut for elevating the same, and a spring for normally elevating the nut, substantially as and for the purpose described.
